Foil transfer device

摘要

A foil transfer device includes an impression cylinder for transporting a printing substrate, a pressure cylinder for pressing a foil web against the printing substrate on the impression cylinder in a transfer nip jointly formed by the pressure cylinder and the impression cylinder, a blower device blowing into an exit region of the transfer nip, and a deflection element for deflecting the foil web. The deflection element is disposed in such a way that the foil web has a web section freely extending from the pressure cylinder to the deflection element. The blower device is disposed on the same side of the foil web as the impression cylinder.

主权项

1. A foil transfer device, comprising:
an impression cylinder disposed on one side of a foil web and configured to transport a printing substrate; a pressure cylinder configured to press the foil web against the printing substrate on said impression cylinder in a transfer nip jointly formed by said pressure cylinder and said impression cylinder; a deflector configured and disposed to deflect the foil web and to provide the foil web with a web section freely extending from said pressure cylinder to said deflector; and a blower disposed on the same one side of the foil web as said impression cylinder and configured to blow into an exit region of the transfer nip, said blower having first blowing openings with a blowing direction oriented towards the printing substrate on said impression cylinder and second blowing openings oriented perpendicular to said first blowing openings, said second blowing openings blowing onto the foil web within the web section extending freely from said pressure cylinder to said deflector.
